AC Method
Identify the wire which when earthed out stops the ignition pack creating a spark. This wire normally runs from the Ignition
switch and/or Kill switch to the ignition pack and will have an earth on it when the machine is not running and be isolated,
have a minimal earth on it or be pulsing when the machine is running.
Connect either the White or White/Red wire to a suitable good earth supply and the remaining wire to the engine kill wire.
When the immobiliser circuit is armed the engine kill wire will be earthed out via the immobiliser circuit and hence will not
run.
Please note: Whilst this method of immobilisation works it is not as secure as the DC immobilisation above. Datatool
recommend the DC immobilisation method is used where possible (even on AC type machines).
A C Immobilisation
The wire being immobilised is 'earthed out' to stop the machine running.
The White tagged wire of the alarm is connected to earth.
The White/Red tagged wire is connected to the wire being immobilised.
